javascript - How to unshorten this js code -


this question has answer here:

i trying understand code of this tic-tac-toe (30 lines of code) game , encountered strange me notation of js.

  1. t[id] ? ai() : move(id, 'ai');
  2. !checkend() ? (role == 'player') ? ai() : null : reset()

i know shortened version of if-statement, don't know how convert it.

thanks in advance.

this ternary operator in javascript.

t[id] ? ai() : move(id, 'ai');

translates to:

if (t[id])     ai(); else     move(id, 'ai');

and !checkend() ? (role == 'player') ? ai() : null : reset() to:

if (!checkend())     if (role == 'player')         ai();     else         ; else     reset();

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
